Abstract
The utility model relates to a cold resistant pliability tensile and elongation cable, and belongs to the wired cable technical field. The cold resistant pliability tensile and elongation cable includes an insulated conductor core and a sheath layer. The insulated conductor core is internally provided with a conductor and externally provided with an insulating barrier; the outside of the insulating barrier is extruded with the sheath layer. The utility model is characterized in that the middle of the conductor is provided with a strengthening core, and a protective layer is positioned between the strengthening core and the insulating barrier. The utility model has the advantages of good microthermal pliability, the continued shuttling movement with a high speed and long service life of the curvature movement under a minor radius.
Description
Technical field
The utility model belongs to technical field of electric wires and cables, particularly relates to a kind of cold-resistant flexible Flexible electric cable.
Background technology
Present known needs at low temperatures, the cable of shuttling movement or bending motion continuously at a high speed or under the minor radius, generally the flexible cable by ordinary construction replaces.This cable is through the following situation of long period: (1) stretches simultaneously or shrinks; (2) with cable carrying cross bar relative friction is arranged; (3) with other cable or cable inside friction is arranged; (4) bear crooked fast, the motion of reversing and rotate; Not only be easy to generate lead twist into spirality, cable rise revolve, heart yearn cracking or failure phenomenons such as fracture, screen breakage or oversheath damage, and the hardness of cable increases under the low temperature environment, even cause sheath to ftracture, have a strong impact on cable drag or servo-actuated under bending property, and cause regular serious stopping production.
Summary of the invention
The utility model provides a kind of cold-resistant flexible Flexible electric cable for solving the problem that existing known technology exists.
The purpose of this utility model provides the cold-resistant flexible Flexible electric cable of characteristics such as a kind of construction of cable is tight, low temperature is soft, life cycle is long.
This construction of cable has carried out optimal design, and the centre is a strengthening core, is made up of fortifying fibre or flexible wire ropes, and fortifying fibre or flexible wire ropes extrude the sheath that shields outward.Be used to drag or during servo-actuated for fear of knotting with guarantee that heart yearn has high bending strength, diameter of wire and pitch have been done optimization process, and stranded bunchy.The low temperature wear-resistant plastic not only has very high mechanical performance and electrical property, and the insulation of extruding is close to and prevents on the lead that it from turning round and round.That cable core is extruded outward is low temperature resistant, wear-resisting, adhesiveness is little and flexible very high oversheath, forms when filling and gusset that twisted wire cooperates extruding, can guarantee well like this oversheath can slow down because drag, bending and the influence that causes to twisted wire.
The utility model adopts following technical scheme:
Cold-resistant flexible Flexible electric cable comprises insulated wire cores and restrictive coating, and conductor is arranged in the insulated wire cores, and insulating barrier is arranged outward, and restrictive coating is extruded in the insulated wire cores outside, is characterized in: there is strengthening core at the middle part of conductor, matcoveredn between strengthening core and insulated wire cores.
The utility model can also be taked following technical measures:
Described cold-resistant flexible Flexible electric cable is characterized in: strengthening core is fiber strengthening core or steel wire rope, and protective layer is the low temperature high-abrasive material.
Described cold-resistant flexible Flexible electric cable is characterized in: between insulated wire cores and restrictive coating lapping layer is arranged.
Described cold-resistant flexible Flexible electric cable is characterized in: lapping layer is flexible strap.
Advantage that the utlity model has and good effect:
This cable is owing to adopted technical solutions of the utility model, compares with prior art, has following characteristics:
1. cable still has good low-temperature pliability in the time of-40 ℃, satisfies normal crooked instructions for use.
2. can be under high speed shuttling movement continuously.
3. can be at bending motion under the minor radius, the running hours bending radius is 5～10 times a external diameter.
4. life cycle is long, can finish 3000000 times circulation.
Cable be subjected to stretching simultaneously or shrink, with cable carrying cross bar relative friction is arranged, with other cable or cable inside friction is arranged and bear crooked fast, reverse and when motion such as rotating, can not produce and twist into spirality, heart yearn cracking, oversheath damages and phenomenon such as screen breakage.
Description of drawings
Fig. 1 is the utility model cross section structure schematic diagram.
Wherein, 1-strengthening core, 2-protective layer, 3-conductor, 4-insulating barrier, 5-lapping layer, 6-restrictive coating.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following example now, and conjunction with figs. is described in detail as follows:
Embodiment 1
With reference to accompanying drawing 1.
Cold-resistant flexible Flexible electric cable comprises insulated wire cores and restrictive coating 6, and stranded zinc-plated soft copper silk conductor 3 is arranged in the insulated wire cores, and stranded zinc-plated soft copper silk has insulating barrier 4 outward.There is fiber strengthening core 1 in cable center, and protective layer 2 is the low temperature high-abrasive material.Insulated wire cores has lapping layer 5, and lapping layer 5 is flexible strap, and lapping layer 5 outsides are restrictive coating 6.
With reference to accompanying drawing 1.
Cold-resistant flexible Flexible electric cable, there is the steel wire rope strengthening core in its cable center.All the other are with embodiment 1.
This construction of cable has carried out optimal design, has very high mechanical performance and electrical property, and the insulation of extruding is close to and prevents on the lead that it from turning round and round.That cable core is extruded outward is low temperature resistant, wear-resisting, adhesiveness is little and flexible very high oversheath, the gusset that formation and twisted wire cooperate when extruding filling, can guarantee well like this oversheath can slow down because drag, crooked and, guaranteed that this cable has good runnability to the influence that twisted wire causes.
Claims (4)
1. a cold-resistant flexible Flexible electric cable comprises insulated wire cores and restrictive coating, and conductor is arranged in the insulated wire cores, and insulating barrier is arranged outward, and restrictive coating is extruded in the insulated wire cores outside, it is characterized in that: there is strengthening core at the middle part of conductor, matcoveredn between strengthening core and insulated wire cores.
